PREDICTOR VALIDITY OF MORPHOLOGICAL AND BASIC MOTOR VARIABLES FOR ASSESSMENT AND MONITORING OF THE KARATE PUNCH WITH THE LEAD ARM (OI-TSUKI)

The purpose of this study was to determine the influence of morphological and basic motor variables on the karate forward punch (oi tsuki) as the only criterion variable, and secondly, to design a test battery for the assessment and monitoring of boys in karate, based on the predictive validity of the tested variables. A system of 25 variables in total -12 morphological, 12 basic motor (the system of predictor variables) and 1 variable of situational moving structure (criterion variable), i.e. the karate punch with the lead arm (oi-tsuki) - was applied on a sample of 82 karate trainees aged between 10 and 14. The results of regression analysis showed that a system of morphological and basic motor variables had a significant impact on punching with the lead arm (p
